I'm running the following WMI script to get the associations between drive letters and physical drives on the system, but for some reason it omits CDROMs/DVD-ROMs. Can someone tell me how to get those as well?
Code:
ComputerName = "."
Set wmiServices = GetObject _
("winmgmts:{impersonationLevel=Impersonate}!//" & ComputerName)
Set wmiDiskDrives = wmiServices.ExecQuery _
("SELECT DeviceID FROM Win32_DiskDrive")

I'm coding this neat little project that's kind of a hack into the SanDisk U3 Cruzer's ability to have both a CDFS and FAT32 File System. This is helpful because the program is burned to the CDFS (It's basically slip streamed as an .ISO in place of the original U3 .ISO), and the settings files (which I've developed as text files) are placed on the root of the flash drive. The program itself is VERY simple actually, except I'm having a slight issue that's really driving me insane:
The drive path of the Flash Drive won't be the same from computer to computer. I.E... The files are "UAI.txt" and "UInfo.txt". The root of the drive on my comp is "I:", but on my laptop is "F:". So if I program the path from my computer as the absolute path, an exception is thrown when the path changes on another computer. I cannot have this happen. It is probably THE MOST crucial element to this program. How can you save and read info if you can't find the files? =P
So I've gone through so many threads and forums trying to find a batch of code to allow me to make the path relative. I've found the following code (modified, of course). It works PERFECT in Debug, but throws an exception once packaged to the CDFS partition:

The drive is connected via USB and the problem I'm having is that, periodically, while my code is executing, the usb drive seems to disconnect and reconnect. (Nothing to do with the program, but the drive itself).I want to find a way to prevent these temporary drive reconnects from interrupting my code. IE, i want to insure that whatever read or write that is requested is actually executed even in the case of a temporary drive interruption.

I also want to know alternative way to get unc path of drive that is also not depend on windows API. As there is a class driveinfo to get all drives (including network) on system. Is there any class that also provide complete or unc path information of Drive.
How do I determine a mapped drive's actual path?
So if I have a mapped drive on a machine called "Z" how can I using .NET determine the machine and path for the mapped folder?
The code can assume it's running on the machine with the mapped drive.
I looked at Path, Directory, FileInfo objects, but can't seem to find anything.
I also looked for existing questions, but could not find what I'm looking for.
We are getting a new server and we already have a Z: drive mapped, and we want to use the same letter and just change the path without touching all machines. I am looking for a simple VBscript to do that. I have one that will remove and one that will add, but I need to have on script.

View 7 RepliesI am trying to copy files from one drive to another. I am a novice at Visual Basic, but here are the facts. I am running Windows XP, and Microsoft Visual Studio 2008. I work at a business where we need to move a small amount of data every Sunday, literally about 100k, a few small files.

This shows all files and folder names on the disc. If I want it to show all files, regardless of the folder they're in, is there a built-in method to do that or do I need to take an entry, identify it as a directory and then use that as my source to read the files in it?
